Hope you had a great break :-)

Indeed.

That would be *excellent*, and I think crucial for the future of rat... 

Would it be easier for a temporary solution to either remove the check for full-duplex (with its implications for some systems), or allow a rat process to only do one side of the problem on request (input or output)? At worst I could then run two rat instances... ugh. I suspect the mbus signalling could get confusing, although they'd be on different identifiers...

Thanks for looking into it!

Cheers,
        Markus
